1 day post laser hair removal and experience very itchy red bumps on legs. Is this normal? And what's the cause? (Photos)

this looks like a mild irritation after laser hair which happens not infrequently. Your doctor can give you a cortisone cream to soothe down the inflammation. This will help, as well as moisturizing the area with a gentle non scented moisturizer

I agree with Dr. Emer. We also see this every so often. It typically happens with the first few treatments. As the hair is reduced, this "reaction" does not occur. We typically see it in patients who have very dense or thick hair. Sometimes extra cooling with ice or a cold roller before and after a treatment can help reduce the chances of this occurring. A topical steroid is very effective. Benadryl can also help with the itching -- but like Dr. Emer said, check with your physician who provided he treatment.
